A moving coil galvanometer has 150 equal divisions. Its current sensitivity is
10 divisions per milliampere and voltage sensitivity is 2 divisions per millivolt. In
order that each division reads 1 volt, the resistance in ohms needed to be connected
in series with the coil will be .
In this I just know that the maximum current and voltage it can read before any resistance connected are 15mA and 75mV.
But now how to proceed .
